Netflix ISP Speed Index Expanded

We have just added February data to the Netflix ISP Speed Index, our monthly update on which Internet Service Providers (ISPs) provide the best Netflix streaming experience during primetime. This month we have expanded our list of ISPs in the United States to the top 60, providing more details on the performance of US ISPs.

Since we started publishing the ISP Speed Index in December 2012 we have tracked the largest broadband providers in the US plus Google Fiber, the guiding North Star for broadband performance in the country. With the expansion, Google Fiber continues to be at the top of the expanded list of ISPs, but Cablevision – Optimum leads the major ISPs.

We expanded the list to provide insight into the performance of many of the smaller providers in the US and to give credit where it is due. For example, Midcontinent, a regional cable provider in Sioux Falls, South Dakota, takes second place in the expanded rankings.

A few additional data points from the February update of the Netflix ISP Speed Index:

  • In the US there were no big shifts in the major ISP rankings in February. We do expect to see Comcast’s performance improve in the rankings next month when we release March data as a result of the recent agreement between Netflix and Comcast
  • In Mexico we now break out Axtel – Extremo, a fiber service, and Axtel Acceso Universal, a WiMAX service. With this break out, Axtel - Extremo lands firmly at the top of broadband providers in Mexico. Elsewhere in Latin America there were no big changes.
  • In the Netherlands UPC left the bottom ranked slot and climbed three spaces, passing Tele2, Online and XS4ALL. In the UK Virgin Media saw its top slot taken over by BT while Com Hem in Sweden and Get in Norway each climbed two spots to land in second place in their respective countries. Elsewhere in Europe there were no major ranking shifts.
The Netflix ISP Speed Index is based on data from the more than 44 million Netflix members worldwide who view over 1 billion hours of TV shows and movies streaming from Netflix each month. The listed speeds reflect the average performance of all Netflix streams on each ISP's network and are an indicator of the performance typically experienced across all users on an ISP network. A faster network generally means a better picture quality, quicker start times and fewer interruptions.

Note: the average performance is below the peak performance due to many factors including the variety of encodes Netflix uses to deliver the TV shows and movies as well as the variety of devices members use and home network conditions. These factors cancel out when comparing across ISPs.

Below is our current ranking of regional ISPs.
